Abstract: An equalizer comprises: an FIR; a trellis decoder coupled to the FIR; a mapper coupled to the trellis decoder; and a decision feedback equalizer coupled to the mapper. The decision feedback equalizer receives the mapped and scaled output of the trellis decoder as input and an error signal is generated by subtracting an output of the decision feedback equalizer from the input to the trellis decoder.

Abstract: An adaptive equalizer comprises a decision device; a decision feedback equalizer coupled to the decision device; an FIR filter coupled to the decision device; and a trellis decoder coupled to the decision device, adapted to provide a reliability output and a decoded output. An error signal is generated by subtracting an output of the decision feedback equalizer from an output of the decision device, the error signal being used to update coefficients of the taps of the FIR filter and the decision feedback equalizer. A magnitude of the change to the coefficients is selected based at least in part the reliability output of the trellis decoder.

Abstract: A digital equalizer comprises a matched filter that, in conjunction with an FIR filter, assures a single peak with substantially greater energy than other peaks caused by ghosts, thereby permitting synchronization even with multiple, arbitrarily strong ghosts caused by strong multipathing, multiple transmitters, or both.

Abstract: A data-directed frequency-and-phase lock loop for an offset-QAM modulated signal comprises a first multiplier that multiplies the signal by the output of a VCO. The output of the first multiplier is phase-shifted by a second multiplier, then convolved by a third multiplier. The output of the third multiplier is split, with each portion being passed through a frequency-shift multiplier and a frequency-and-phase lock loop. The output of the two frequency-and-phase lock loops is summed and returned to the VCO to complete the feedback loop.

Abstract: Cubic boron nitride/diamond (cBND) composite films with excellent adherence to various substrates and their fabrication method are disclosed. The cBND composite confining cBN can be prepared without any amorphous/turbostratic BN (aBN/tBN) incubation layers. The cBND composite is established on the compatibility of structural and physical properties of two superior materials: cBN on top and diamond beneath. The underlying diamond is adapted to the substrate of choice using a variety of methods which may include prescratching the substrates, bias enhanced nucleation, etching for depleting undesirable chemical elements, construction of buffer layers and gradient buffer layers for the isolation of undesirable chemical elements or/and adaptation of physical properties. The diamond nuclei are preferably formed either by bias-enhanced nucleation or by pre-scratching the substrate prior to nucleation.

Abstract: A data-directed frequency-acquisition loop capable of generating a frequency error having a magnitude and direction from a double sideband suppressed signal comprises a first multiplier that multiplies the signal by the output of a VCO. The output of the first multiplier is convolved by a second multiplier. The I output of the second multiplier passes through a first low-pass filter. The filtered I output and the Q output are then multiplied by a third multiplier. The output of the third multiplier is filtered through a second low-pass filter, amplified, and return to the VCO to complete the feedback loop.

Abstract: The present invention deals with the generation of sharp single crystal diamond tips and the arrays of these tips, and their fabrication technology. The invention combines the deposition of synthetic diamond films with reactive etching processes. Upon the diamond orientation prepared and reactive etching environment with considerable directivity of ions, single crystal diamond tips with different apical angles can be fabricated. Very sharp diamond tips with an apical angle of no more than about 28° and a tip radius smaller than 50 nm are fabricated on pyramidal-shaped [001]-textured diamond films by subsequent reactive etching., The technology is based on selective etching of sp2- and sp3- hybridized carbons by the activated constituents of an etching environment, in particular based on atomic hydrogen, in a way similar to ion bombardment, which contributes to overall etching and local conversion of diamond to graphitic phase promoting further etching with chemically activated species.

Abstract: A data-and-pilot directed frequency-and-phase lock loop for an offset-QAM modulated signal having a pilot signal comprises a pilot acquisition loop and a pair of data-directed acquisition loops. The pilot is extracted from the main signal by a pilot filter, then used both by the pilot acquisition loop and to remove the pilot from the signal to the data-directed acquisition loops. The outputs of the pilot and the two data-directed acquisition loops are summed and returned to the VCO to complete the feedback loop.

Abstract: The present invention relates to a method of manufacturing sputtering targets doped with non-metal components including borides, carbides, nitrides or oxides. A powder process is utilized whereby alloyed powders, which contain non-metal elements of B/C/N/O and non-metal containing phases of less than ten microns in microstructure, are blended, canned and subjected to press consolidation. The sputtering targets of the present invention avoid spitting problems during sputtering of the target material on a substrate.

Abstract: A power distribution control system for a hybrid fuel cell vehicle is provided. The system includes a high energy converter (HEC) for providing current from an electrical bus to the battery, or from the battery to the bus. As a vehicle load changes, the HEC adjusts the battery current flow. A current command is sent to a fuel cell controller so that the fuel cell current output is adjusted. As the fuel cell current output changes, the HEC further adjusts the battery current flow, until there is a zero net current flow to and from the battery. At this point, a state of equilibrium is reached and the fuel cell provides all the current required by the vehicle loads.

Abstract: Sputtering targets are produced which have an intermetallic stoichiometry which makes them ductile enough for maching and sputtering. The targets are produced from elemental or alloy powders or alloys, at least one of which is of very fine particle size, e.g., −400 mesh. The elemental or alloy powders are blended, canned, subjected to hot isostatic pressing at low temperatures and high pressures, formed into a billet, and machined to form the target.
